MILLING-MACHINE VISE.

SPECIFICATION forming part of Letters Patent No. 652,441, dated June 26,1900.

Application filed April 11,1900. Serial No. 12,413. (No model.)

T0 ctZZ whom it may concern.-

Be it known that LEDWARD J.MCCLELLAN, a citizen of the United States,residing at the city of New York, in the borough of Manhattan and Stateof New York, have invented certain new and useful Improvements inMilling- Machine Vises, of which the'following is a full, clear, andexact description.

This invention relates to milling-machines for working metal, and hasspecial reference to the means for mounting and adjusting the vise whichis used to hold the work upon the table or slide of the machine.

A form of vise commonly employed on milling-machines consists of a pairof jaws, one of which is movable with respect to the other, said jawsbeing swiveled or pivoted upon a base, which in turn is adapted to bebolted to the sliding table of the machine. WVith such a construction itis possible to support the vise in one plane only, which plane ishorizontal; but it is often found desirable to mount the vise in anupright position upon the slide in order to use the machine to the bestadvantage; and it is one of the objects of my invention to so constructthe base to which the vise is swiveled that the vise can be mounted ineither a horizontal or vertical plane.

Another object of my invention is to provide improved means forswiveling the vise to the base, whereby large and true bearingsurfacesare provided, and an eflicient lock,

may be utilized for holding the vise in any position in which it may beadjusted upon its base.

With the above objects in View the invention consists of a base for thevise having two surfaces standing at an angle to each other and means inconjunction with each surface whereby either of them may be secured tothe slide or table of the milling-machine, and thus support the vise ineither of two positions, depending upon the surface utilized; and theinvention further consists of the combination, with a vise and its base,of a swivel connection between the two consisting of male and femaleparts having the shape of the frustum of a cone, with their conical surfaces forming a bearing upon which the parts turn.

The invention also consists of certain fric tional locking devicesarranged to cooperate with said surfaces to hold the vise in anyposition with respect to the base.

The invention will be described with pan ticularity in connection withthe accompanying drawings, in which Figure l is a perspective view ofthe vise and base connected together. Fig. 2 is a plan of the base, andFig. 3 is a section of the base on line m a; of Fig. 2.

No part of a milling-machine is shown, because the same forms no part ofthe present invention. It will be understood, however, that the vise andits base, hereinafter described, may be attached to the sliding table ofany form or construction of milling-machine.

Referring to the drawings by letter, A indicates an ordinarymilling-machine vise, and B the base to which it is swiveled. The visemay be of any approved construction; but as here shown consists of aplate a, having a fixed jaw a, and a second plate a constituting an adjustable jaw and fitted to slide upon the plate Ct by turninga screw aThe base B consists of a cylindrical block, one face 19* of which atright angles to its axis is planed ofi to make accurate fit against thesurface of the sliding table of the milling-machine. Its opposite faceis provided around a portion of its circumference with a scale I) for apurpose which will hereinafter appear. It is also provided atdiametrically-opposite points with two ears I) I), having notches bwhich admit of the introduction of bolts par allel to the axis forsecuring the said planed surface against the slide of the milling-machine.

The base is provided with an extension 12 having a planed surface I) atright angles to the other planed surface described and parallel to theaxis of the base, which planed surface is also adapted to be securedagainst the surface of the sliding table of the millingmachine and forthis purpose is provided with ears 19 containing notches b for theintroduction of fastening-bolts in a position at right angles to thesurface 19 be seen that the base may rest flat upon its side or upon oneedge and may be readily se It will thus cured to the table in either ofthese positions by means of suitable bolts inserted at the placesdescribed and engaging with the table.

For swiveling the vise to the base the latter is provided with a largecentral opening a, one end of which adjacent to the scaled side isformed into a conical bearing surface or seat the smaller diameter ofwhich is at the surface upon which the scale is marked. Into this seatis fitted a disk e, the periphery of which is conical, thus making thedisk the frustum of a cone. The disk is passed to its seat from belowand is secured to the plate a p of the vise by means of a center bolt 0and an eccentrically-placed bolt 0 Thus the disk and its seat form aninterlocking or dovetail connection between the vise and the base, whichpermits the vise to swivel around the axis of the base. The vise will beprovided with a mark or index at a convenient point to be used inconnection with the scale I) to fix the vise at a determined angle uponthe base. For securing the vise in an angular position, into which itmay be adjusted, the base is provided with two radial passages ninetydegrees apart, containing shoe f, the faces of which are exposed in andform a part of the conical surfaces of the bearing in the base. Theseshoes are backed up by ad justing-screws g, by means of which they maybe forced against the conical surfaceof the disk with sufficientpressure to lock the disk and the vise attached to it against any rotarymo tion. To adjust the vise, it is of course necessary to first slackenthe bolts.

Having described my invention, I claim 1. The combination of a vise formilling- 2. The combination of a vise for millingmachines and a base towhich the vise is swiveled, said base being provided with two sets ofpassages for fastening bolts, one set of passages being parallel to theaxis of the swivel-joint, and the other at right angles thereto.

3. The combination of a milling-machine vise, a base therefor having twosupportingsurfaces and a swivel connection between them, consisting of adisk attached to one member and having the shape of the frustum of acone, and a seat formed in the other member and having a correspondingshape, and means for locking the members at any desired relativeposition.

4. The combination of a vise for millingmachines, a base therefor havingtwo supporting-surfaces, a swivel connection between them consisting ofa disk attached to one member and having the shape of the frustum of acone and a seat in the other member having a corresponding shape, andradial shoes forming a part of said seat and provided with means foradjusting them in a radial direction, substantially as described.

In witness whereof I subscribe my signature in presence of twowitnesses.
